The video explores the role of genes and DNA in living organisms and introduces CRISPR, a gene-editing tool derived from a natural bacterial immune system. CRISPR uses Cas9 proteins and guide RNA to target and edit specific genes, offering potential treatments for genetic diseases and applications in agriculture and medicine. However, ethical concerns and the unpredictability of long-term effects pose challenges.
